PowerShell Requires Chilkat v11.7.0+

Create a vCard (Contact) QR Code

See more QR Code Examples

Demonstrates a QR code that adds a contact to a phone when scanned. The text is a vCard, the standard format for contact details: lines between BEGIN:VCARD and END:VCARD, each ending with CRLF. A vCard is fairly long, so the symbol is larger than one holding a web address. Leave out the fields that are not needed to keep it small. PowerShell

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  The second argument of AppendLine is cktrue to end each line with CRLF.
